ATTENTION: MRC has proudly manufactured Power Packs since 1947 and has sold more than 1 Million products to satisfied customers in North America without any issue during this time. Evidently, Rapido Trains, a relatively new train manufacturer has allegedly not made their locomotives suitable for use with MRC's 1300 & 1370 Power Packs, which have used the same tried and true technology for the last 25 years with UL Certification.
